MINNEAPOLIS, MINNESOTA, A CORPORATION EDGE-SCOURING ROLL.

Application filed September 7, 1920.

To (/ZZ 107mm may concern Be it known that I. Grouse ORVILL Teeny. a citizen of the United States. residing at Minneapolis. in the county of Henuepin and State of Minnesota. have invented certain new and useful Improvements in Edge- Scouring Rolls; and I do declare the following to be a full, clear. and exact description of tae invention. such as:- will enable others d in the art to which it appertains to and use the same.

My present invention has for its object to provide an improved edge scouring roll especially adapted for use in finishing sole edges. in shoe factories and repair shops. and to such ends generally stated. the in vcn'tion consists of the novel device and combnations of devi: es hereinafter described and defined in the claims.

In the accompanying drawings. which illust :te the invention, like characters indicate like parts throughout the several views.

Referring to the drawings:

Figure l is an axial section of the improved edge scouring roll;

Fig. 2 is a section on the line Q-2 of Fig. l; and

F ig. 3 is a view corresponding to F 2, but showing the two-part wheel opened up.

The complete scouring roll comprises two disk-like flanges preferably having hubs se cured to a driving shaft or spindle. and a diametrically split or two-part wheel. The wheel sections may be variously formed integral or otherwise. and as shown, each halfwheel section comprises a semi annular wooden body l and metallic. preferably cast. dish-like cam plates 5 rigidly secured thereto. as shown by means of screws (5. The two wheel sections 4 are connected by a hinge T, and one of the wheel sections is provided with laterally spaced rings 8 preferably formed integral with its cam plates These rings 8 are of a size to closely lit the driving shaft 9.

The cam plates 5. in their outer faces are formed with eccentric cam grooves 10, but here it may be stated that these cam grooves are only necessary in the cam plates of the outwardly swinging wheel sections, but are shown as provided in the cam plates of the other wheel section because, in practice. the cam plates are first made as complete disks Specification of Letters Patent.

and then sawed sections.

The flanges 11, noted above, are disk-like elements with flat inner faces and outstanding hubs 12 that are rigidly secured to the shaft 9 by set screws 13. The flat faces of the flanges 11 are so spaced that the wheel sections fit closely between the same. For cooperation with the cam grooves 10 of the outswinging wheel section, the flanges 11 are provided with alined inwardly projecting cam pins or studs 14.

hen the closed wheel is turned so that the cam pins 14 are close to the free portions of the outswingiug wheel section, the latter may then be freely swung to its open position shown in Fig. 3. The periphery of the two wheel sections l are provided. preferably. with pliable facings 15 that are covered with the scouring cloth or paper 16. the ends of which are turned inward between the wheel sections, as shown in Fig. 2. when the wheel is closed. To securely hold these inturned ends of the cloth or paper 16. the wheel sections are provided with barbs l7 and barb seats 18.

As is evident, when the wheel, is opened up as shown in Fig. 3, the scouring cloth or paper may be readily removed and replaced with new scouring cloth or paper.

\Vhen the wheel sections have been closed, the closed wheel should be turned in the direction of the arrow marked on Fig. 2, so as to cause the cam pins 14 to act on the inner portions of the cam grooves 10 and thereby cam the wheel sections together.

In applying the wheel section that has the rings 8 thereon, to the shaft, attention must be paid to the direction in which the shaft, see Fig 3. will rotate when in action, and said wheel must be applied in such a manner that when the shaft is rotated, the backward driving; action on the wheel due to the friction. will tend to rotate said Wheel in a direction to cause the cam pins 14 to more tightly close the wheel sections together.

A further important novel feature should be noted. to wit; that the quite sharp, but slightly rounded peripheral edges of flanges 11 project beyond the applied scouring cloth or paper, so that the one or the other thereof, in finishing a shoe sole, will always be between the shoe sole and the shoe upper or diametrically to form the leather body and will positively prevent deiacing or the latter by keeping the same out of contact with the abrading surface of the scouring cloth or paper.

It is important to note that the projecting peripheral portions of the two hub flanges are smooth and unbroken so. that there are no rough or sharp edge portions that can out or damage the leather of the shoe upper even it it should come in contact therewith. Obviously, cam slots or the like running to the edges of the hub flanges would produce cutting portions that would cut the leather it coming in contact therewith.

' lVhat I claim is:

1. An edge scouring roll comprising laterillly spaced axially alined rigidly connected rotary hub flanges, at least one of which has a lateral cam projection, and a split scouring wheel one section of which is rotatively mounted between said flanges and the other section of which is movable to and from working position and isprovided on at least one side with a cam surface, which under rotation of the closed wheel cooperates with said cam projection to lock the two wheel sections together.

2. An edge scouring roll comprising laterally spaced axially alined rigidly connected rotary hub flanges, at least one of which has a lateral cam projection, and a split scouring wheel one section of which is rotatively mounted between said flanges and the other section of which is movable to and from working position and is provided on least one side with a cam surface, which under rotation of the closed wheel cooperates with said cam projection to lock the two wheel sections together, the peripheral edge of least one of sa idflanges projecting beyond the periphery of the closed wheel.

An edge scouringfroll comprising laterally spaced axially alined rigidly connected rotary hub flanges, at least one of which has a lateral cam projection, and a split scouring wheel one section of which is rotatively mounted between said flanges and the other section of which is movable to and from working position and is provided on at least one side with a cam surface, which under rotation of the closed wheel cooperates with said cam projection to lock the two wheel sections together, the peripheral edge of at least one of the said flanges projecting beyond the periphery of the closed wheel,

said pro ection being smooth and unbroken.

.41. A scouring roll comprising laterally spaced axially alined rigidly connected rotary hub flanges, and a split scouring wheel one section of which is rotatively mounted between said flanges and the other section of which is movable to and from working position, said flanges having opposing cam projections and said movable wheel section having eccentric cam surfaces with which said cam projections are engageable, under rotation of the closed wheel, to lock the two wheel sections together and to said flanges.

5. A scouring roll comprising laterally spaced axiallyalined rigidly connected rotary hub flanges, and a split scouring wheel one section of which is rotatively mounted between said flanges and the other section of which is movable to and from working position, said flanges having opposing cam projections and said movable wheel sections having eccentric cam surfaces with which said cam projection are engageable, under rotation of the closed wheel, to lock the wheel sections together and to said flanges, the peripheral edges of the said flanges being smooth and unbroken and projecting beyond the periphery of the closed wheel.

6. A scouring roll comprising a scouring wheel and hub flanges on the opposite sides thereof and said hub flanges having smooth unbroken peripheral edges that projectbeyond the periphery of said wheel.

In testimony whereof I aflix my signature.

GEORGE ORVILL TERRY.
